COMBINED STOP AND DRAW COCK. .i

SPECIFICATION forming part of Letters Patent No. 270,3'99, dated January 9, 1863.

` Application filed May 2G, 1882. (No model.)

To all whom it may concern Be it known that I, EDWARD DAssAU, of the city of Brooklyn, in the county of Kings and State ot' New York, have invented acer 5 tain new and useful Combined Stop and Draw Cock, of which the following is a specication.

The object of my invention is to provide a cock which, when placed in the service-pipe of a building-in the cellar, for instance-will to serve all the purposes ofa stop-cock, and which, while open to admit water to the house or building, will also serve as a draw-cock to enable water to be drawn fornse in the cellar or carried through a hose attached directly to I5 the plug of the cock for street-washing or other purposes.

My invention consists in a cock ot' novel construction, hereinafter particularly described and claimed, whereby the desired end is attained.

In theaceompanyiug drawings,Figurc l represents a sectional view of'a cock embodying my invention, with the plug turned so as to discharge water through the draw-nozzle on the plug. Fig. 2 represents a similar view, with the plug turned so as to admit water to the service-pipes only, the port leading to the cavity in the plug being closed; and Fig. 3 represents a transverse section on theline, Fig. l. I

Similar letters of reference designate ,corresponding parts in all the tigures. ,V

A designates the shell ofthe cock, which is here represented as constructed with Shanks L A,.wl1ereby it may be secured in the servicepipe ot a house or buildingI by solder joints.

B designates the plug, which tits in ataper seat in the shell in the usual way, and is provided with a handle, B', for turning it.

YVhen secured in the service-pipe the cock is intended to stand as shown in the drawings, and the water passes to thehouse or building through a direct water-way, d, in the shell A, and la corresponding water-way, a',in the plug B, as clearly shown by arrows in Figs. l and 2.

In the shell A, above the direct water-way a, is a port, b, opening into the taper seat for the plug B, and from said port a passage, b', leads to the direct water-way a upon the outlet side ofthe cock.

'the nozzle B3 at the head.

In the head ot' the plug B is a cavity, B2, which is separate from the water-way d', and on one side of which is a port, c, which ranges with the portb in the shell, and when the plug is turned into the position shown in.Fig.2the port cis closed and watercan only owthrough the direct water-way a a to the house or. building. By turning the plug halt' round and into the position shown in Fig.1 the watercan still ow through the direct water-way a a to the house or building, and as the port c in the plug B is now in coincidence with the port b in the shell A the water can also pass Ithrough the passage b' and ports b c into the cavity B2 in the plug. The plug B is provided at the head with a bend, B3, which forms a nozzle or bib, which is in communication with the cavity B2, and from which water may be drawn by turning the plug to the position shownin Fig. v

l. The nozzle or bib B3 is provided at the end with the external screw-thread, d, to which a hose-coupling, O, may be applied, as shownin dotted lines in Fig. l; and when the plug' is turned to the position shown in Fig. l water may be conveyed through the hose for Streetwashing or other purposes.

Then the plug B is turned so that the vrater-way c stands across the shell the cock will serve as a stop-cock and prevent the passage ot' water to the house or building or through Vhen thus turned to serve as a stop-cock it is desirable that the water in the house-pipes should be allowed to waste, and this I provide for by forming waste openings or vents e in the plug diametrically opposite each other, as shown in Fig. 3, and ranging with the port b in the shell. Oonsequently it will be seen that when the plug is turned a quarter ot' a turn iu either direction from the positionsbown in Figs. l or 2 oneor the other of tbeveut-openings e will be brought opposite the port b, and the water from the house-pipes can waste into the cavity B2 in the plug and through the nozzle B3.

It will be observed that by this construction I provide for wasting from the house pipes without the necessity of forming any waste openings or vents in the shell.

Stop-cocks in cellars are generally set so close to the wall that the plugs can be turned IOO l ter-way to said port, and the plug B,couslrueted with the Water-way a', the draw nozzle or bib B3, the cuvityB, which lis independent of and separate from the waiter-way a', and the port c into said cavity ranging with the port l in the shell, all substantially as and for the purpose herein described.

in but one direction, and two Waste openings or vents e are provided, so that the plug will waste when turned in either direction, thus making a cock which muy be set either right or lel't handed.

That Iclaini us my invention, und desire to secure by Letters Patent, is-
